The correct answer is: C. Both A and B
Air is a mixture of gases, with nitrogen (N2) and oxygen (O2) being the two most abundant. Nitrogen makes up about 78% of the air, while oxygen makes up about 21%. The remaining 1% is made up of other gases, such as argon, carbon dioxide, and water vapor.
Nitrogen is a colorless, odorless, and tasteless gas. It is the most abundant element in the Earth’s atmosphere, making up about 78% of the air. Nitrogen is essential for life, as it is used by plants and animals to create proteins and nucleic acids.
Oxygen is a colorless, odorless, and tasteless gas. It is the second most abundant element in the Earth’s atmosphere, making up about 21% of the air. Oxygen is essential for life, as it is used by plants and animals to breathe.
Both nitrogen and oxygen are gases that are colorless, odorless, and tasteless. They are both essential for life, as they are used by plants and animals to create proteins and nucleic acids, and to breathe. Therefore, air shows the properties of both nitrogen and oxygen.
Option A is incorrect because air is not only made up of nitrogen. It is also made up of oxygen and other gases.
Option B is incorrect because air is not only made up of oxygen. It is also made up of nitrogen and other gases.
Option D is incorrect because air does show the properties of both nitrogen and oxygen.
